Reаd this descriptiоn оf а study аnd then answer the fоllowing questions about the study. A sociologist believes that people with smart phones will watch television less and get better grades in school. So she takes a sample of 200 U.S. teenagers who do not have cell phones. She also believes teenagers watch more television and have more friends than adults. Then she gives a smart phone to 100 of them but not the others. One month later she asks all 200 students how many friends they talk with every day, their grades in school, and how much time they watch television. What is the experimental group in this study?
